In 1972, Bush had a Top 20 hit with "I'll Be There," which led to a deal with RCA and a Top Ten hit with his song "Whiskey River," which later became Willie Nelson's signature song. Just as Bush reached the brink of stardom, he started to lose his vocal range. Doctors were not able to diagnose the reason until 1978, when they found he had a rare neurological disorder, spastic dysphonia. This did not prevent his recording, but his career soon took a downturn. Working with "voice builder" Gary Catona in 1985, Bush was able to bring back about 70 percent of his original voice. The following year he and Darrell McCall teamed up to record the successful honky tonk album Hot Texas Country. He then assembled a large country band and began performing around San Antonio.
In 1994, he and the band released Time Changes Everything and launched a major tour; the 1998 follow-up, Talk to My Heart, was regarded as one of his finest recordings in many years. Bush continued a prolific release schedule into and during the new millennium, on occasion even releasing two albums in a single year. His recordings during this period included Lost Highway Saloon and Sings Bob Wills (both 2000), Green Snakes (2001), Honkytonic (2004), Texas State of Mind and Devil's Disciple (both 2006), and Texas on a Saturday Night (co-billed to Justin Trevino) and Kashmere Gardens Mud: A Tribute to Houston's Country Soul (both 2007). ~ Sandra Brennan, Rovi
